• Suspension: AST coilovers and camber tops, COBB sway bars, end links and toe arms, and HARDRACE and Perrin bushes and mounts.
• Brakes and driveline: Alcon and Paragon brakes, GrimmSpeed and GFB short shifters and Drive Shaft Shop driveshafts.
• Aero: APR carbon splitters, wings, mirrors and brake cooling plates.

• Sedan or hatch: the GV sedan and GR hatch share most parts, but wings and rear aero are body-specific. APR's STI wing is listed for 2011-2014 sedans.
• STI or WRX: the STI has the EJ257, a 6-speed gearbox and Brembo brakes. Many WRX (GE/GH) parts fit, but check engine, brake and driveline parts.
• Tune: intake, exhaust and fuel upgrades need a tune. The COBB Accessport listed here is the Australian-spec version.

Have a qualified workshop fit suspension, brake, fuel and engine parts. Get a wheel alignment after any suspension change, and bleed and road-test the brakes after brake work. Intake, exhaust and fuel changes need a tune, such as a COBB Accessport map; ask us if you're unsure.
